Can't seem to output my CSS from the new WordPress Theme Customizer 3.4

Hello, been playing around with this for almost 2 days now, and I can’t seem to get it working.

I’m playing around with the new Theme Customization API, found here:
http://codex.wordpress.org/Theme_Customization_API

I have been following the steps from the codex, and I have been following the steps from Ottos great write up. But no matter what I do I can’t seem to output my settings to wp_head.

Here is my code using the class from the codex:

but it outputs only:

<!--Customizer CSS-->
<style type="text/css">
</style>
<!--/Customizer CSS-->

I did also try this method:
http://pastebin.com/1EDknt12

but it outputs only:

<style type="text/css">
.navbar-inner { background-color:; }
</style>

Somewhere down the line it feels like I’m missing something or thinking about this the wrong way.
